, ELECTRICALLY-OPERATED SWITCH.

SPECIFICATION forming part of Letters Patent No. 588,871, dated May 7,1895.

Application filed January 12, 1895. Serial No. 534,614- (No model.)

in electrically operated switches, formed of a series of magnets, anarmature between said magnets, a rod supported on a frame and secured tosaid armature, and an arm fastened to a switch with a system oftogglelevers be: tween said arm and said rod, and. contact points withconnections with eachseriesof magnets, whereby either series may beoperated, and the switch moved, suitable mechanism on the car beingadapted to complete the circuit. 1

Figure 1 represents a plan view of aswitch embodying my invention. aside elevation of the operating mechanism on a car. Fig. 3 represents anend elevation of the same. Fig. 4 represents an end elevation of part ofthe operating mechanism on an enlarged scale. Fig. 5 represents a viewshowing the course of the current to the points of contact.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings: A designates the rails of the main line of arailway, and B the switch thereof. Between the rails, near the switch B,is situated the box 0, in which are placed a series of magnets D, D, andE, E, having an armature F between the said series. G designates a framesecured to the bottom of the box 0, and from said frame rise the guidesH, and mounted therein is a rod J, which is secured to the armature F.

Fastened to the rod J, is one end of a system of levers K, which arepivoted to the box 0 by the pin L, the otherend of said levers beingattached to a link M, which connects the same with an arm N, the latterbeing passed through the side of the box C, and secured by the axial pinP to the switch B. The system of lovers K consists of two toggle leverspivotally connected at L and to the link M and two levers which are eachpivotally Fig. 2 represents connected at one of their ends with the rodJ and at their other end with one member of each of the toggle leversintermediate its ends and its pivotal connection at L whereby themovement of the rod J, moves the inner end of the link M in thedirection of the length of the said link.

Q and Q designate contact points suitably insulated, which are situateda little distance in front of the switch, between the tracks A.

The point Q is connected with one series of magnets by the conductor R,and the other point, Q, is connected by the conductor S with the otherseries of magnets, said conductors R and S being protected by a suitablecovering T. Bonds U connect the box 0 with the tracks A.

A designates a bar. which is supported on the frame of the running gearof a car, and insulated therefrom by the pieces B. Passing through saidbar A are the plungers C, which are held in raised or normal position bysprings D, said plungers carrying rollers E on their lower ends.

F, G designate toggle levers, which are connected with the bearings ofthe rollers E and with a suitable part of the car.

Fastened to the free end of one of the levers F is a cord or wire N,which passes over a roller H, and is attached to one arm of anelbowlever J, which is supported by an ear K on the car, the other armof said elbow lever F having pivoted thereto the post L, which passesthrough the floor of the car, and is in reach of the motorman.

The bar A is suitably connected with the main conductor by'the wire M.

The operation is as follows: If it is desired to switch from the mainline to the side track, the motorman depresses one of the posts L,

. so that it moves the elbow lever J, and forces down the plunger 0, theroller E contacting with the point Q. This forms a circuit, and themagnets D, D, are charged and attract the armature F. Moving with thearmature F is the rodJ, which operates the system of levers K, so thatthe arm N is moved and with it the switch B, as shown in dotted linesFig. 1, and the car is switched to the side track. The switch B willremain in the last position until operated by the next car, if desired.If the switch B is in the right place,

the plungers need not be operated, and will pass above the contactpoints, as shown in Fig. 4. To return the switch B to its position, theother plunger 0' is operated, and with the contact point Q completes thecircuit, whereby the armature is attracted and operates the parts, theswitch-moving so that the car can proceed on the main track.

Any number of magnets may be employed.

Having thus described my invention, what I claim as new, and desire tosecure byLetters Patent, is-

1. In an electrically operated switch, a box, two sets of magnetstherein, a frame secured to said box, guides on said frame,a rod mountedon said guides, an armature for said magnets, secured to said rod, aswitch connected by a system of toggle levers with said armature andmechanism on the car being adapted to complete the circuit as described.

2. In an electrically operated switch, a box, two sets of magnetstherein, an armature between said set of magnets, a frame on said box, arod supported on said frame and secured to said armature, a switch, anarm fastened thereto, a system of toggle levers between said arm andsaid rod and contact points connected with the series of magnets,suitable mechanism on the car being adapted to complete the circuit,substantially as described.

3. In an electrically operated switch, main, and side rails, a switch, abox with two series of magnets therein, a common armature for saidseries, a rod secured to said armature and movable in guides in saidbox, an arm connected with said switch, asystem of toggle leversconnected to said rod and by a link to said arm, said parts beingcombined substantially as described.

4. In an electrically operated switch, a bar suitably supported from acar but insulated therefrom, plungers movable in said bar, and carryingrollers at their lower ends, springs for raising said plungers, togglelevers pivoted to each other and to a bearing of said rollers, an elbowlever mounted on the car, an operating post therefor, a connection forsaid elbow lever and toggle levers, and a conductor from said bar to anelectric supply, said parts being combined substantially as described.

5. In an electrically operated switch, a switch rail, a box with theseries of magnets D and E therein, the armature F between said series,of magnets, the contact points Q, Q, the conductors R and S leading fromsaid contact points to said series respectively, the rod J connectedwith said armature F, the system of toggle levers K connected with saidrod, the arm N passing through the side of the box and connected withsaid switch rail and by a link with said levers K said rod I beingmovable in the guides II and said box having bonds U. said parts beingcombined substantially as described.

(3. In an electrically operated switch, a series of magnets, an armaturefor said magnets, a rod secured to said armature, toggle leversconnected with said rod, an arm secured to the said levers, a switchhaving an axial pin which is fastened to said arm, contact points whichhave conductors to the different series of magnets, and means foroperating the parts, substantially as described.

7. In an electrically operated switch, a box, two sets of magnetstherein, an armature be tween said sets, a rod connected with saidarmature, a switch rail connected by a system of toggle levers, withsaid rod, two contact points one of which is electrically connected withone of said sets of magnets, the other point being connected with theother set, and mechanism for making an electric circuit with eithercontact points, said parts being combined substantially as described.
